AM9800 Description
The AM9800 is a direct PWM driver IC designed for three-phase brushless motors. Also, by using highly silent PWM drive, switching current of the phase with a smooth slope reduces the sound of slewing motor, and makes high-efficiency drive a reality by a synchronous mutation. The device is build-in lock protection.
